Kaiju I'd Like To See In Possible Future Monsterverse Movies

As we all know, the contract between ToHo and Legendary Pictures ends pretty much after Godzilla vs Kong. But with the all the hype that's going around for King Of The Monsters, many fans like me are hoping that ToHo gives Legendary the ability to make more Monsterverse movies. If ToHo gives Legendary Pictures the rights to more of their monsters, which ones would be brought into the Monsterverse?  We all know that Mike Dougherty wants to include Biollante and Gigan into the Monsterverse, and I'm totally down with seeing them in the possible future. I actually want to see Gigan a little bit more, mostly due to all of the awesome concept art I've seen of him. Here's an example: I'd also really want to see Destoroyah. Since we know that Godzilla will transform into Burning Godzilla (I'm refusing to call it Fire Godzilla. It just doesn't sound right) in King Of The Monsters, it kinda makes sense to at least introduce the concept of Destoroyah into the Monsterverse. SPOILERS AHEAD- I know that Burning Godzilla won't have the Red-Spiral Ray, instead, he has the ability to produce nuclear pulses just by walking. And it may make even more sense to see Destoroyah in the Monsterverse, as it was teased a few months back that While Godzilla and Ghidorah are fighting, either Monarch or the Military will deploy the use of an Oxygen-Destroyer type weapon on them, with Godzilla being badly injured in the process, while Ghidorah comes out just fine. Mechagodzilla is kind of tough though. It's main role in the Godzilla series is to protect humanity from Godzilla and other monsters like him. (Excluding the Showa Mechagodzilla. He was a villain.) The only possible reason that I can see Mechagodzilla into the Monsterverse is when Sally Hawkins says that "They're Everywhere" in the second trailer for the movie, possibly referring to other monsters like Godzilla, Ghidorah, Rodan, and Mothra. If this is the case, then Mechagodzilla's role in the Monsterverse will most likely be a defender of the Earth, protecting humanity from Monsters like Godzilla that may appear. Finally, I have my last possible introduction: Anguirus. A LOT of people have been open to the idea of Anguirus being in the Monsterverse, mostly due to the mysterious mountain-kaiju that was briefly seen in the second trailer. I myself thought that it was Anguirus, and was excited that he may be seen in the Monsterverse. I actually have a lot of respect for him. I guess you could say that he's one of my favorite monsters. The reason why I have so much respect for him is that he's usually seen as Godzilla's unofficial sidekick, as well as an underdog in many fights that he has participated in. I feel like he needs some love too, and that's exactly what IDW did. In the first issue of IDW's Godzilla:Legends, Anguirus is fighting a monster that most people thought he would quickly die to. In the first issue, Anguirus fights Destoroyah, and it is one heck of a fight. Destoroyah does seem to get the best of Anguirus at first, but Anguirus manages to pull off the seemingly impossible, turning the tables against Destoroyah and actually WINNING. Anguirus my friend, you have my respect! And that's pretty much the kaiju that I'd like to see in the future. If there are any other monsters that you'd like to see that i did't mention, leave a comment below. I'd love to hear everyone's thoughts!
